Show me your RACK - Page 59

post #1741 of 2096
23" racks are also a standard. If shopping off CL, bring a tape measure, if rack model # unknown.

I prefer the square holes, functionally. Cage nut stripped? Toss it, and grab another.

I picked up a server rack from a university surplus center, destined for scrap. Also harvested a bunch of shelves.

Really? I've never seen anything but 19" in near 30 years in electronics.
Worthwhile info though for others to make sure they don't buy something they can't use.

23 or 24" racks are used in the U.S. mainly by the telephone companies. They are mostly 2-post racks.

I was going to say the same thing....Also, my rack used M6 cage nuts (it's just what I started with), but the MA trim strips used 10/32 screws. I just had to buy some new cage nuts, replace them where needed, and I was done. Normally there is no need to use both types, I just didn't want to change out all the ones I had already done on the back side of the rack.

How many 23" audio video components have you guys ever seen?

I own one, a 23" wide power conditioner. I have seen rack ears for 23" racks as an option, but life is simpler to
stick with a 19" rack..

There is also a new 'half width' rack standard, released in the last couple years. 10 5/8" width, for smaller components.

It was about 5 years ago that an AVSer bought a 23" telco relay rack, mistakenly, for his AV components. Made it work with some 2x4 wood extension pieces. Pic has been removed.

I have one 23" shelf I mistakenly purchased. Everything else is 19".

I actually prefer the round hole unthreaded kind of rack. Not the square hole, nor the kind with threads on the rack rails themselves. The threaded kind can strip. But at least then you can add a cage nut to them. The square ones are a pain in the ass to add the nuts into the holes when you've got a full rack. Or when you want to move things around without tearing everything apart. Yeah, you generally shouldn't do it that way... With the round cage nut kind you can slide a nut up/down a position or two without pulling the gear out. Word of advice, buy double the amount of cage nuts you think you'll need... you'll still come up short.

Also note there are different kinds of screws. There are even some that have a post that screws in and a knurled nut on the face. This way you can screw in the post and have a point on which to rest the gear while muscling it into place. Just be sure to use the SAME thread size, whichever style you chose.

Word of advice, put anything that might require service on sliding rails. Yes, the rails can be pricey. But the ease with which you can service stuff far offsets the hassle of having to pull gear totally out of the rack whenever you need to change something in it. As in, computers that might be getting upgrades. There are a variety of schemes for dealing with the wires. Some are 'less worse' than others but they're all a bit of an adventure.

For items less likely to get altered, or ones that have hard connections to in-wall wiring, you're probably better off not putting them on sliding rails. This so you don't wreck the wiring and connectors.

I'm not familiar with these. i've used threaded and square cahe nut. Could you post a link of the round ones you described?
post #1749 of 2096
The hole is round, the nut itself is typically a normal hex shape but welded to a spring steel L-bracket that clamps to the rack rail.

I believe these are also referred to as slide or clip nuts. Here's an example of them:


Here's a couple of informative link discussing screws and racks in general:

And to clarify on rack slides, you need slides that fit the case in question. Not all cases are the same width. As a result the slides will need to deal with getting that case to fit. The narrower cases generally aren't too much of a problem, as the mounting bracket for the slide will have some leeway on the mounting holes (either open or elongated). But a case that's wide will have trouble fitting in the rack AND having slides next to it. The vendors for these wider cases will often sell slides specifically designed for them. Also note that a very heavy case may require more than one set of slides. I've got a very heavy 24-drive server that requires two sets of very narrow slides to fit in the rack. Just one set of slides wouldn't handle the weight, especially not when extended.

I never see racks on Craigslist or Ebay. I emailed a fella a while back about one, but he flaked out on me rolleyes.gif

What are you searching for on eBay? I did a quick search and found a ton of racks. Here is the link, take your pick: http://www.ebay.com/sch/i.html?_sacat=0&_nkw=server+rack&_frs=1

Admittedly I don't use eBay much, I look on Craigslist to try to score something cheap. This morning I looked on eBay but was searching local to me. Though with the shipping options on there I shouldn't be so scared smile.gif

I guess I got lucky then. Literally my very first search on Craigslist turned up a used MA WRK 37-26 LRD just a few minutes from my front door. I shot a PM to neurorad to confirm it was an acceptable Rack and went to pick it up over the weekend. The search terms that neurorad provided were helpful and the use of search tempest as well.

Then I searched for rack shelves and found someone with brand new shelves for a reasonable price who is practically my neighbor. Going to pick them up soon as well.

Looking forward to finishing my room and installing the gear in my rack. I will post some pics when it is done.
post #1755 of 2096
I'm glad you like the WRK. It's a great rack, for a freestanding unit. It may be hard, though, to get that 'built in', flush-mount look, with a WRK; it will be much easier than with the wall-mount rack you were also considering. wink.gif

Wow! I need to move to Kansas

Also check with local computer or electronic recyclers or salvage places. I picked up a pair of Sun racks for my gear reasonably cheap from one across town from me.

The other rack, the one I'll be using for the HT gear, I picked up via craigslist. If you've got an SUV (and some bungee cords) you can get a rack home in one. So search a little farther than just your immediate home town. Mine was from south of Woodbridge, a good hour's drive. The drive back with an open rear hatch was entertaining. The soundproofing on the Grand Cherokee really hides the tremendous roar the Hemi makes when you floor it on the highway...

These racks all look amazing...I am definitely interested in the Middle Atlantic racks.....Question for rack owners...i have a fanless HTPC...I built it so i wouldnt hear ANYTHING while i was watching my movies....arent all those racks with their fans noisy? especially since many of them are in the same room with you??
post #1759 of 2096
There are quiet fans. If I were you I would put some in my PC as well.

I tried for all quiet gear in my racks too, but it seems impossible anymore: some components have such noisy fans it seems like they added it as an afterthought: I usually end up changing the fan to a quiet type if I can as mentioned.

so now I just think of it as 'white noise' and deal with it...smile.gif

Not really, I also replace any audible fans with near silent( <10dBA ) fans, from http://www.coolerguys.com/fans.html .
post #1762 of 2096
Thanks guys for the inputs!! I guess just getting quiet fans and dealing with the noise seems to be the consensus....

Electronics life span is severly shortened by chronic high temps. Does your processor have a fan? Yes it does and all the heat pushed out by the fan stays around the rest of your pc components.
post #1764 of 2096
My htpc case is a fanless design...it uses copper heat pipes from the CPU to pull the heat away out towards the case which has fins to dissipate the heat
post #1765 of 2096
This is also why a lot of racks end up with plexiglass doors on them. Either jump through hurdles trying to silence the gear or just hide it behind an acrylic panel. Now, even with a door you would still want to aim for quieter gear to start with.
post #1766 of 2096
Either way, cooling is a necessity. Your hard drives put off quite a bit of heat as does a power supply.
post #1767 of 2096
Hey, everyone that has a free standing rack, Casters on carpet?

My rack backs up to a wall and super hard to access the back, has anyone had experience with a tall rack on casters? Should I worry about tipping, carpet dmg, etc...

Also MA casters vs buying from home depot.
post #1768 of 2096
At my last house I had my rack on casters because I was renting and could not cut a whole in the wall. The rack was so heavy that it bent the casters and the rack was not movable. Since then I bought my house and put it in the wall, but if I didn't put it in the wall I would have tried using track rails or something else other than casters. I think that over time it could possibly damage your carpet.

Hey jsketto,

Yes your PC may be a fan-less design, but read up on how temp effects gear, that PC may be rated fan-less in an open environment but the second you throw it in a rack it will directly effect the temp of the surround equipment. You need to keep the temperature of your rack below a certain temp or else the life of the device drops 20/30%.

refer to this:middleatlantic.com/pdf/ThermalManagement.pdf‎
post #1770 of 2096
You do not want the temp above 85 degress F and I thought that I read somewhere a while back that it could actually shorten the life span to about 50%. Could be wrong about that but for sure nothing above 85 degress.
